Hi Everyone,
I've got this problem that occurs only when i turn to the right, it jerks. It occurs at both high and low speeds but with revs around 2-2.5K. Usual conditions are: Car is warm, turning tight-ish sweeping bends, large roundabouts or large and fast diameter circles. I have no problems at intersections/tight carparks and parking (needs speed). My car is manual.
What occurs through the turn/bend is what i can best describe as JERKY: The sensation is like being in a very responsive gear such as first, accelerating up to speed (say 4k revs) and then suddenly letting your foot off the accelerator and then slamming it back on, on and off repeatedly. Its that agressive.
This of course occurs in whatever gear i'm in. The above is an example of what it feels like through the turn. If i were to be able to pick up enough speed in the wet, the response would certainly induce lift off oversteer.
A few thoughts:
1. At first i thought my injectors were playing up: But noticed it ONLY occured on right turns
2. Thought it was fuel sloshing to one side of the tank and not having the fuel pump pick up petrol: But i had a full tank of fuel
3. Friend suggested it may be HICAS related: But since HICAS only affects steering the rear wheels, and the motors used to turn them couldn't possibly cause such an agressive response from the engne.
4. Diff related/Power Steering: Unsure. It certainly feels like the engine. Unless somehow the diff is suddenly binding up and releasing itself instantaneously. I don't think power steering would cause such a response to the engine. Similar to that of air-con, the engine easily compensates for the power drawn to operate them.
5. Fuel filter/AFM/Fuel-related: It only occurs through right turns though.
If anyone can please throw some ideas/suggestions/first-hand experiences with this sort of problem that would be greatly appreciated, before i spend the little money that i have. To me, its a real nutter.
Thanks all,
Will.
